Two things I'm seeing... one, you're using very old firmware on both radios... I'd update that. Second, the peer side in the pictures signal is occasionally dropping down to -95, which is a really really bad signal. I'd try to figure out why the peer side's signal is dropping so low occasionally.

Hi Refaat

Just a couple of things I'm seeing at the captures you upload it.


Your using 5700 channel (140) 


Your Link is up with -72 Dbm (Means Signal Strength)


Your Path shows 9.6 Km according to your captures.


According to the spectrum analyzer capture:

Master  has -72 Dbm (Co-channel and Adyacent-Channel Interference)

Slave (Peer) Has -90 Dbm (Seems really good specturm you got up peer site)

Your need to upgrade both Radios Master/Slave to latest version, that being said. gotta use ASO on the Master Side so you will get beter performance up there. 

Any help you need, do not hesitate in contact me.

Best Regards.

Unless you try to do something beyond what you have already mastered, you will never grow.
